TDQS

A3.7/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations are absent, so the description carries the burden, and it delivers meaningful details: cost of 1 credit, no charges on empty results/failures, and cache behavior. It discloses failure cost, freshness behavior, and output nature, though it does not address auth or rate limits.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short and front-loaded with output characteristics, then cost, then caching. The only minor issue is slight redundancy: '(1 credit)' and 'Costs 1 credit' state the same information twice.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given only two parameters, one required, and no output schema, the description covers the essential invocation context: what kind of data is returned, cost implications, and cache behavior. It is sufficiently complete for an agent to select and call the tool correctly, though a bit more detail on the response shape would help.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline is 3. The description does not add material semantics beyond the schema: cache=true and default fresh behavior are already documented in the schema, and the URL parameter is fully explained there. It does not clarify parameter semantics further.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly identifies the resource as a Snapchat profile and specifies what it returns: a stable identity card, millisecond timestamps, and media type image/video. While it lacks an explicit verb like 'fetch' or 'get', the meaning is unambiguous and the platform distinction separates it from sibling profile tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for Snapchat profiles through the tool name and first phrase, but it does not explicitly state when to use this tool versus alternatives or mention exclusions. It offers practical advice about cache=true and cost, but no direct comparison to other profile tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
